摘　　要：为了查明海底管道周边采砂区的范围、水深和地貌等情况,本文首先对其进行全域侧扫声呐扫测,寻找采砂活动痕迹;其次,辅以单波束水深地形数据,进行现场初步解译,摸清采砂活动区空间位置分布后,再采用多波束测深系统开展精细水深地形调查;最后,对采砂区与管道之间开展地层剖面结构调查,较全面地完成了海底某管道周边采砂区的地形地貌探测。结果表明,应用多种探测技术方法可以较好地探测海底地形和地貌,本文所采用的技术方法和工作流程可为相关工程应用提供参考。In order to find out the scope,water depth and landforms of the sand mining areas around the submerged pipeline,the surveying areas were scanned firstly by the side-scan sonar to find the traces of sand mining activities in this paper.Then the single beam water depth and topographic data was used to perform the field preliminary interpretation,so to find out the spatial distribution of the sand mining areas,and the multi-beam sounding system was used to carry out detailed water depth and topographic surveying.Finally,the stratigraphic section structure between the sand mining areas and the pipeline selected in this paper was surveyed,and the topographic and geomorphologic detection of the sand mining areas around the submerged pipeline is completely finished.The results show that the underwater topography and landforms can be precisely detected by various detection technologies.The technical methods and workflow used in this paper can provide useful references for related engineering applications.
